Why would anyone doubt Hillary Clinton's character? Sexism, she explains in her new book.

Hillary Clinton's forthcoming account of the 2016 presidential campaign contains a 64-page chapter called "Sisterhood," 36 pages of which are expressly dedicated to her experiences as a woman in politics, according to a copy obtained by the Washington Examiner. In that subsection of the chapter, Clinton outlines how she believes sexism and misogyny hampered her bid for the presidency in 2016, arguing in part that questions surrounding her authenticity and trustworthiness were the result of those prejudices.

"...Even though this sounds like bragging and bragging isn't something women are supposed to do," Clinton writes, "I haven't just been a participant in this revolution. I've helped lead it."

As she's claimed more than once in the months since her loss to Donald Trump, Clinton states clearly in "What Happened" her belief that "sexism and misogyny played a role in the 2016 presidential election," but draws distinctions between both forces, asserting sexism is something "we can all buy into … from time to time" while misogyny is "something darker."

"Both sexism and misogyny are endemic in America," Clinton contends, pointing readers specifically to "look at the YouTube comments or Twitter replies when a woman dares to voice a political opinion or even just share an anecdote from her own lived experience," as proof.

As for 2016, Clinton says "Exhibit A" in the role sexism played in her electoral defeat, "is that the flagrantly sexist candidate won."

"A whole lot of people listened to the tape of him bragging about sexually assaulting women, shrugged, and said, ‘He still gets my vote,'" she writes.

The chapter pulls no punches on President Trump.

"Throughout the 2016 campaign, my staff would come to me wide eyed. ‘You'll never believe what Trump said today. It was vile,'" Clinton recalls, adding, "I always believed it. Not just because of who Trump is but because of who we can be at our worst. We've seen it too many times to be surprised."

The former first lady calls Trump's comments in the Access Hollywood tape "horrible … just horrible" and alleges he brought women who have accused her husband of sexual assault to the debate "to divert attention from his own ugliness."

After reflecting for a page on mistakes she made to earn the suspicions about her authenticity and trustworthiness that showed up in polling during the campaign, Clinton writes, "I think there's another explanation for the skepticism I've faced in public life. I think it's partly because I'm a woman."

During a meeting early in her campaign with Facebook COO Sheryl Sandberg, Clinton says Sandberg told her: "The more successful a man is, the more people like him. With women, it the exact opposite. The more professionally successful we are, the less people like us."

"That the basic fact that sexism is alive and well should still be up for debate," Clinton says, is "maddening."

She weighs in on the Democratic Party's current battle over whether it should use support for abortion rights as a litmus test for candidates as well, arguing pro-life Democrats such as Tim Kaine who are "personally opposed" to abortion but don't support government restriction of abortion are acceptable.

"But when personal views on abortion become public actions -- votes on legislation or judges or funding that erode women's rights -- that's a different matter. We have to remain a big tent, but a big tent is only as strong as the poles that hold it up," Clinton contends, referring to herself as "pro-choice, pro-family, and pro-faith."

Clinton also endorses the terms "mansplaining" and "intersectionality," both of which are popular with the radical feminist movement. "Mansplaining," she writes, "the second I heard it, I thought, 'Yes! We needed a word for that!' "

Reflecting on her decision not to confront Trump for "breathing down [her] neck" during the second presidential debate, the former secretary of state claims, "A lot of people recoil from an angry woman, or even just a direct one," going on to cite as evidence recent dust-ups involving Sens. Elizabeth Warren, D-Mass., who was famously interrupted by Senate Majority Leader Mitch McConnell in February, and Kamala Harris, D-Calif., who drew criticism during her questioning of Attorney General Jeff Sessions in June.

In addition to Sandberg, Clinton invokes other feminist favorites in the chapter, including Handmaid's Tale author Margaret Atwood and Beyonce, the latter of whom she says "reclaimed" her infamous 1992 quote, "I suppose I could have stayed home and baked cookies and had teas, but what I decided to do was pursue my profession," as a "message of independence" during a pre-election rally last year.

In "On Being a Woman in Politics," as the subsection is titled, Clinton looks in retrospect on experiences as early as her time taking the law school admissions test in a room full of men to her husband's failed 1980 gubernatorial bid to her time in the Senate all the way up to 2016. She grapples with the pitch of her voice, her wardrobe choices, and her role as a mother and wife.

"Men aren't naturally more confident than women," Clinton writes on the section's final page. "We tell them to believe in themselves, and we tell women to doubt themselves. We tell them this in a million ways, starting when they're young."
